LIQUID-DELI VERING DEVICE.

Specification of Letters Patent.

Patented May 2 t, 1910. Divided and this application filed March 19,

To all whom it may concern: I l

Be it known that l, l/VILLIAM B. Hanvns, I a citizen of the UnitedStates, residing at Sunbury, in the county of ilorthuinberlaml and Stateof Pennsylvania, have invented certain new and useful Improvements inLiquid-Delivering Devices; and I do hereby declare the following to be afull, clear. and exact description of the invcntion,'sucl1 as willenable others skilled in the art to which it appertains to make and usethe same.

My invention consists in the novel features hereinafter describedreference being had to the accompanying drawing which illustrates oneform in which I have embodied my invention and said invention is fullydisclosed in the following description and claims.

Referring to the drawings, Figure 1 represents a front elevation of ameasuring pump embodying my invention. Fig. 2 is a vertical sectionalview of the same.

This application is a division of myformer application for LettersPatent of the United States, for improvements in measuring pumps, filedJune 9, 1908, Serial No. 437,568.

The object of my invention is. to provide a pump for delivering;quantities of liquids particularly such as gasolene, kerosene and thelike.

In carrying out my invention I employ a pump cylinder and piston orplunger, the latter being operated by the rotation of a shaft carrying apinion gearing with a rack on the pump rod, which is entirely incloscdwithin the pump cylinder or an extension of 1 the same, so that noevaporation of the liql l I l l uid or escape of fumes is permitted.This is particularly desirable in handling gasolene. the fumes of whichmixed with air form, as is well known, a. highly explosive and dangerousmixture. The pinion and rack teeth are preferably so proportioned thateach i revolution of the pinion moves the plunger to deliver a definitequantity of liquid, say one qua-rt, the capacity of the cylinder being];a multiple of this quantity, say one gallon, and the rack providing forfour revolutions l of the crank shaft to move the plunger from itslowest to its highest position. I also provide a dripless siphondelivery spout, and in connection therewith a sight gage to show thelevel of the liquid above the plunger.

In Figs. 1 and 2 I have shown my invention applied to a type of pumpadapted for use especially with a storage receptacle. barrel or tanklocated in another apartment and below the room in which the pump isplaced. as in the cellar of a building, or a tank setin the groundoutside of the building as the case may be. In these figures Arepresents the pump barrel or cylinder provided with a base B, and asubstantially spherical head C. D is the piston or plunger located inthe cylinder and provided with the valve {J and a piston or pump rod (1having a rack thereon. The rack engages a pinion a on a shaft 6 ournaledin the head C and provided at one side thereof with a gland throughwhich it projects, and the projecting portion of the shaft (2 isprovided with a crank or handle E at its end, for operating the shaft 6by hand.

Within the head C, an idle roller c is preferably supported on the sideof the rack opposite the pinion e, to hold the rack in en 'agemcnt withthe pinion and guide it in its vertical movements.

The base B has an apeiturein it into which is screwed the supply pipe I,which extends into the supply tank, barrel or receptacle, whereverlocated, and is provided at its lower end with the check valve K andsieve or filter is. I prefer to provide the base B with an extension Bhaving an annular flange Z), and forming a drip pan to catch anyoverflow, when filling vessels with the device. The drip pan is providedwith a central aperture through which the liquid drains, and from whichit is conducted by a drain passage or pipe L to the storage or supplyrecemacle. The pipe or passage ll is preferably provided with a checkvalve Z to prevent the escape of fumes from the storage or supplyreceptacle.

The upper end of the pump cylinder or barrel is provided with a closedtubular extension C secured to the head C to permit the rack to moveupwardly as required, and which also serves as an air chamber. Thedevice is also provided with a delivery spout of peculiar form. In Figs.1 and 2 l have shown this spout formed integral with and connected tothe head C, which brings the nozzle of the spout at a convenient heightfrom the drip pan B for filling: vessels. The delivery spout C extendsoutwardly and upwardly from an aperture 0 in the head C, and adjacent toits highest. point is provided with a cut oil valve 0', below whichextends a discharge or nozzle 0. A curved lip 0 extends upwardly fromthe lower edge of the discharge orifice o within the head, to a pointslightly below the level of the seat of valve 0, as indicated in Fig. 2.WVhen the piston is rising in the pump cylinder it forces the liquidabove the lip and upwardly to the valve seat aperture, and there is avery slight compression of air in the upper part of the cylinder. Whenthe piston stops it stops sudgLenly, as is usual with a hydraulicpiston, ant. the reaction of the air cushion above the liquid forces theliquid out quickly until it reaches the level of the lip 0 when itinstantly stops with even a slight rebound in some instances, leavingthe liquid in the spout below the level-0f the valve seat, hence therewill be no drip after the operation of the device is stopped. This isdesirable as it avoids waste of liquid and the stoppage of all flow isprac; tically simultaneous with the stoppage of the piston.

of hermetically sealing the pump and prethe escape of fumes or theinventing either gress of am may In order that the operator tally withthe delivery orifice, and will preferably be provided with a mark asindicated at w in line with the upper edge of the lip 0 The operation ofthe device will be clear from the drawings and foregoing description andneed not be specifically described.

\Vhat I claim and desire to secure by Letters Patent is 1. In a liquiddelivering device, the coin bination with a pump cylinder provided atits upper end a piston working in said cylinder, of a horizontallydisposed delivery spout connected with the cylinder below the airchamber and having a portion extending above its point of connectionwith the cylinder, and pro I vided with a lip within the air chamber,extending upwardly from the lower edge of the communicating aperturebetween the cylinder and said spout.

2. In a liquid delivering device, the combination with a pump cylinderprovided at its upper end with a closed air chamber, and a pistonworking in said cylinder, of a horiz'ontaily disposed delivery spoutcommuni- The valve 0 serves the function know the exact level of theliquid in the pump before beginning to operate it, I provide a sightgage C of usual type which is secured to the apparatus in linehorizonwith a closed air chamber, and

eating with the cylinder by an aperture 10- cated adjacent to but belowthe upper end of the air chamber portion of the cylinder, and providedwith a lip extending inwardly and upwardly from the lower edge of saidcommunicating aperture, said spout having portions between said apertureand its delivery end extending above the upper edge of said lip, andhaving a valve seat located adjacent to the horizontal plane of the upper edge of said lip, and a valve in said spout engaging said seat.

3. In a liquid delivering device, the combi nation with a pump cylinderprovided at its upper end with a closed air chamber, and a pistonworking in said cylinder, of a hori zontally disposed delivery spoutcommunicating with the cylinder by an aperture 10- ealed adjacent to butbelow the upper end of the air chau'ib'er portion of the cylinder, andprovided with a lip extending inwardly and upwardly from the lower edgeof said l communicating aperture, said spout having 1 portions betweensaid aperture and its dej livery end extending above the upper edge l ofsaid lip, and having a horizontal valve j seat located above thehorizontal plane of l the upper edge of said lip and a vertically l l ll i I i l l i I 1 l l i I i 1 l l i l l i l 1 l l l movable valveengaging said valve seat.
